Abstract We synthesized pyrene-containing amphiphilic fluorinated copolymers p(C7F15MAA/PyMMA)s through free radical polymerization. The pyrene composition ratio was readily tuned from 0.6 to 3 mol% with different monomer feeding ratios, designated as p(C7F15MAA/PyMMA0.6) and p(C7F15MAA/PyMMA3). p(C7F15MAA/PyMMA) nanoparticle films were prepared by dropcasting copolymer solutions onto substrates with the mixture of AK-225 and acetic acid. The copolymer nanoparticle film surfaces exhibited superhydrophobic character with a water contact angle of greater than 160° and low surface free energy (< 19 mN m−1). The emission from the p(C7F15MAA/PyMMA0.6) nanoparticle film was dominated with monomeric emission, while that from the p(C7F15MAA/PyMMA3) nanoparticle film showed mainly excimer emission. The dissolved oxygen sensing performance of the nanoparticle films was also investigated in terms of the different emission modes.

含芘两亲性氟化共聚物的合成与自组装纳米结构及其氧传感应用

摘要 我们通过自由基聚合合成了含芘的两亲性氟化共聚物p(C7F15MAA/PyMMA)s。芘组成比很容易从 0.6 到 3 mol% 调整到不同的单体进料比，指定为 p(C7F15MAA/PyMMA0.6) 和 p(C7F15MAA/PyMMA3)。p(C7F15MAA/PyMMA) 纳米颗粒薄膜是通过将共聚物溶液滴涂到具有 AK-225 和乙酸混合物的基材上来制备的。共聚物纳米颗粒膜表面表现出超疏水特性，水接触角大于 160°，表面自由能低 (< 19 mN m-1)。p(C7F15MAA/PyMMA0.6)纳米颗粒薄膜的发射以单体发射为主，而p(C7F15MAA/PyMMA3)纳米颗粒薄膜的发射主要为准分子发射。
